In addition, each of winches 5 to 7 is mounted on the rotating frame by using a mounting structure standardized in the same class. On the other hand, left and right deck frames 18 and 19 are divided into sections on which different pieces of equipment are mounted, and the sections are separately attached to the rotating frame 17.

Abstract: A carburetor for an internal combustion engine has an intake pipe having a throttle valve plate therein. An annular venturi tube is disposed upstream or downstream of the throttle valve plate inside the intake pipe. The annular venturi tube is located at a predetermined interval with the throttle valve plate. The annular venturi tube has a fine continuous annular slit or four or more annularly arranged fuel discharging pores so as to atomize the fuel thereat. Atomization is always carried out near a position where a fastest air moves so as to improve the atomization and a uniform air-fuel mixture, thereby improving an output, fuel consumption and exhaust gas emission of the internal combustion engine.

Abstract: A partitioning member for dividing a connecting pipe into at least two exhaust passageways is provided in the connecting pipe, which is attached to an exhaust side of a silencer. A valve mechanism is operable to vary the passageway area of one of the exhaust passageways. With this structure, for example, when an engine is rotating at low revs, exhaust gas is discharged from the exhaust passageway without the valve mechanism, while when the engine is rotating at high revs exhaust gas is simultaneously discharged from the exhaust passageway having no valve mechanism and a passageway provided with the valve mechanism. Therefore, it is possible to reduce exhaust noise when the engine is rotating at low revs.

Abstract: A control device for an antilock braking system is disclosed. When a target angle of a crankshaft provided to a servomotor of an ABS that is closer to a turning limit than to a predetermined updating stop angle, the target angle is set at the updating stop angle or the vicinity thereof. An expander piston is displaced to an open end side corresponding to the turning limit of the crankshaft by an elastic force of a return spring after being displaced to a position corresponding to an updating stop angle for the crankshaft or the vicinity thereof. This arrangement permits reliable, accurate displacement of the expander piston to a predetermined position corresponding to a turning limit of the crankshaft without causing the servomotor to consume needless electric current.
